How Morse numbers are structured
Every number uses five total signals. Digits 1 through 5 begin with dots and add one more dot each time. Digits 6 through 0 flip the pattern and begin with dashes. Because of that symmetry, the number system is much easier to remember than it first appears.
- 1 = one dot, then four dashes
- 5 = five dots
- 6 = one dash, then four dots
- 0 = five dashes
